A microprocessor-operated valve is held in a showerhead to shut off flow of water if a leak detector measures any water leakage. The valve is mounted in a conduit in the showerhead and operated to shut off water flow if the water leak detector senses leakage from the showerhead. An electric motor is held in the showerhead and actuated to drive a gear train to close the normally-open valve and shut off water flow through the conduit.
